Orioles top pitching prospect Dylan Bundy underwent an injection of platelet-rich plasma in his sore right forearm/elbow area Monday in Florida and will not do baseball activities for at least six weeks while he rests and rehabs.

“It’s good news that they’re recommending rest and therapy and then a resumption of the throwing program,” Orioles executive vice president Dan Duquette said. “It seems like a bump in the road.”

Bundy, 20, has been dealing with tightness in his forearm and elbow since late March. A MRI showed no structural damage to the elbow, but Bundy wanted a second opinion and asked to see renowned surgeon Dr. James Andrews.

So the organization and its fan base was holding its collective breath that the 2011 first-rounder would not need surgery on his electric right arm.

Andrews met with Bundy on Monday in Gulf Breeze, Fla. He recommended and then administered the PRP injection. Andrews prescribed rest for six weeks — a time in which Bundy will stay in Sarasota, Fla. and work with the organization’s medical staff.

“We’re hoping we’re talking about June. I hope. We’ll see. We are going to take the conservative approach and make sure we get it resolved,” Showalter said. “He’ll have a good support staff down there with him. He just has to listen to what the doctors say he should be doing.”

Bundy, listed as the sport’s No. 2 prospect by Baseball America heading into this season, is not the first young Orioles pitcher to have a PRP injection. Last spring Zach Britton, who made his Orioles debut Monday night in Seattle, underwent two rounds of the procedure.

As part of the procedure, the blood is enriched with platelets and is designed to stimulate the healing of bone and soft tissue.
